Title: Why the Copenhagen Interpretation Doesn’t Work and Why It’s Popular Anyhow.

Abstract: conventional wisdom holds that since the advent of the first full theories of quantum mechanics in the mid-1920s, the Copenhagen interpretation has been the default interpretation of quantum mechanics, and has enjoyed the support of a majority of physicists ever since. This is not the case. While it is indeed true that a majority of physicists have long professed that they subscribe to the Copenhagen interpretation, the plain fact of the matter is that there is no single coherent position known as the Copenhagen interpretation, nor has there ever been one. Moreover, none of the positions that go by the name “Copenhagen interpretation” do a good job of solving the measurement problem, the central interpretive problem at the heart of quantum foundations. Nor do they evade the nonlocality that is dictated by Bell’s theorem. In this talk, I will give an overview of the history of the Copenhagen interpretation from 1926 to the present, explain its multiple inconsistencies and failures, and attempt an answer at a persistent puzzle: why does the Copenhagen interpretation remain popular among physicists despite its manifest flaws and the existence of multiple superior alternatives?

Abstract: as our understanding of the universe and its basic building blocks extends to shorter and shorter distances, experiments capable of probing these scales are becoming increasingly difficult to construct. Fundamental particle physics faces a potential crisis: an absence of data at the shortest possible scales. Yet remarkably, even in the absence of experimental data, the requirement of theoretical consistency puts stringent constraints on viable models of fundamental particles and their interactions. In this talk I’ll present some of these constraints and discuss their applications for cosmology, string theory and more.

Entropy is among the most important but also most perplexing concepts in physics. It is also a polymorphic concept: introduced in thermodynamics, we now find it in statistical mechanics, quantum mechanics, information theory, and black hole physics, to name just the most obvious. In this summer school, we will systematically explore the various concepts of entropy as they are used in state-of-the-art physics and evaluate their philosophical interpretations.

The summer school will consist in lectures and research talks. Participants will have the opportunity to present their work in short talks. We would like to emphasize that we are happy to accept scholars at any stage of their career (from students to senior faculty) as participants.

Abstract: Hugh Everett III’s pure wave mechanics, sometimes known as the many-worlds interpretation of quantum mechanics, was proposed as a solution to the quantum measurement problem. Both physicists and philosophers of physics have repeatedly claimed to be able to deduce the standard quantum probabilities from pure wave mechanics alone. We will consider why this is impossible, then consider how Everett himself understood quantum probabilities. This will involve clearly distinguishing between typical and probable quantum worlds.

Abstract: I argue that if we take the standard formulation of special relativity seriously, causation is frame-dependent. Thus, many ordinary causal claims require a parameter to specify the relevant frame of reference. This is in contrast to the widely-accepted belief that the causal structure of the world is objectively and absolutely determined by the light cone structure. Any event that can affect another (so the thought goes) must do so via light or matter, and the spacetime structure will tell us which of those came first, absolutely. For instance, according to Carl Hoefer (2009, 694, italics in original), if we assume that all signals travel slower than or equal to the speed of light, “we may take the light-cone structure of Minkowski spacetime as equally representing the causal structure of spacetime.” I argue that causation in relativistic spacetime is not so simple. Events can be extended in space and time, and events can be related to one another by distance and duration. Yet, according to special relativity, extension in space and time (i.e., distances and durations) are not invariant—they depend upon relative motion. Therefore, when ordinary events enter into causal relations, they do so relative to frames of reference, which can yield different causes and different effects. If you want to keep your promises, or bring about one outcome rather than another, you should take note of your reference frame.

Abstract: I will discuss some recent work by Tim Maudlin concerning Black Hole Information Loss. I will argue that there is a paradox, in the straightforward sense that there are propositions that appear true but which are incompatible with one another, and discuss its significance. I will also discuss Maudlin’s response to the paradox.

Abstract: This talk will consider strategies for extending the wave function realist interpretation of quantum mechanics to the case of relativistic quantum theories, responding to the arguments of Wallace and Timpson (2010) and Myrvold (2015) that this cannot be done.
